CHA|N-MACH|NE FOR THE MANUFACTURE OF CORRUGATED CARDBOARD.

Specification of Letters Patent.

Patented Jan. 23, 1906.

Original application filed April 1,1903, Serial No. 150,660.- Dividedand this application filed August 31, 1904. Serial No. 22 2 900- To aZZwhom, it may concern.-

Be it known that I, OAMILLE THIEBAUT, a citizen of the French Republic,residing at Vitry-sur-Seine, France, have invented certain new anduseful Im movements in Chain- Machines for the Manu acture of CorrugatedCardboard, of which the following is a specification.

v This invention relates to improvements in chain-machines for theurpose of obtaining a novel corrugated cardboard.

Plaited, waved, or corrugated cardboards as hitherto manufactured do notpresent sufficientrigidity for large packages. It is true that in somecases there has been stuck to one or both sides of sheets of corrugatedcardboard a smooth sheet uniting all the corrugations situated u on thesame side; but the product so obtained is expensive, inextensi- 1e, andonly imperfectly resists compression exerted at right angles .to theoriginal plane surface 'of the corrugated sheet.

' compressionwhich it may have to support The conditions which should befulfilled by corrugated cardboard are as follows: first,

the cost rice should be exceedin ly small;

second, t e weight should be as sma l as possi-' ble; third, thecardboard should present the greatest possible resistance to theeifortsof either in the direction of the original p ane surface beforecorrugation or at right an les to this planeyfourth, constant extensibiity for the purpose of permitting the cardboard view showing therelativev to be shaped asregularly'aspossible to the objects to bepacked and of causing it to assume the form of packages of the mostvarious kinds, such as fia ons or bottles. I obtain a cardboard fulfiling all these conditions by means 'of the improvement in knownchainmachines hereinafter described.

In the accom anyin drawings, Figure 1' is a section on the ine A F ofFig. 2. Fi 2 is a lan view of my novel corrugated car board. igu3 is anelevation of the fluted shaft for driving the endless chains. Fig. 4 isa planpositions of the fluted-shaft and itsendless chain, and Fig. 5 isa sectional view showing two endless chains pressing a sheet ofcardboard; Fig. 6 is a sectional view of theendless belts and rollers,-

showing the fluted arrangement of the same; and Fig.7 is a plan view ofone of the rollers.

In chain-machines the driving is effected by means. of gear-Wheels castupon a shaft.

treated is of small thickness, the folds or undulations are producedwithout difiicult'y;

When the paper or o er su sEi'nce id 2;

but,when the substance to be treated is of hich it affords in theoperation of the ma.

0 inc, permits of obtaining a corrugated cardboard resenting all thecharacteristics enumerated above. It permits in particular of giving tothe blades of the chains absolute rigidity, obviating give, so as tocertainly effect the displacement of the cardboard and the ressingaction of the blades. This novel cardboard is provided in the usualmanner with corrugations, which areformed' alternately above-and belowthe original plane of the sheet; but instead of being smooth andcontinuous throughout their length these corrugations are formed withprotuberances,ribs, or projections f at greater ,or le'ssintervals onefrom the other, which, so to speak, convert each of the folds,undulations,.o r corrugations. into a reinforced beam and the sheet ofcardboard as a whole into a series of rigidly-connected reinforcedbeams. It will be readily understood that these protuberances impart tothe corrugations considerable capacity for resisting pressure which maybe exerted in a direction at right an les to theoriginal plane of thesheet-of card oard and that they render unnecessary the employment ofthe auxiliary sheet of cardboard stuck to the summits of each of thecorru ationswhich has been referred to above.- File absence of thisreinforcin -sheet results in a diminution of weight and reduction of thecost of manufacture, since the protuberances in question are obtainablein a single pressing operation. These protuberances also impart to thesheet perfect extensibility and permit it to adapt itself to all kindsof packages.

Too

Having now particularly described and as' certained the nature of mysaid invention and in what manner the same is to be performed, I declarewhat I claim is 1. A machine for the manufacture of corrugatedcardboard, having the driving-shaft provided with grooves throughouttheir entirelength, cha1ns passing over said dnvingshafts having ontheir under side-grooves corresponding to the'grooves of theshafts, andmeans for passing a sheet of cardboard between the chains of themachine.

2. In a chain-machine for the manufacture of corrugated cardboard,grooves on the entire length of the driving-shafts, engagingcorresponding grooves of the under sides of the chains for the purposeof moving the latter.

3. Ina machine for the manufacture of corrugated cardboard or paper, thecombination of a plurality of endless belts having corrugatedv outerfaces and grooved inner faces and arranged one above the other withtheir adjacent runs in contact, and a plurality of A rollers forsupporting and driving the belts, and provided with grooves coactingwith the grooves of the belts.

4. In a machine for the manufacture of corrugated cardboard or paper,the combination of a plurality of endless belts havin undulatorycorrugations on their outer aces and grooveson their inner faces andarranged one above the other with their adiacent runs coacting.

In witness whereof I havc'hereunto set my hand, in the presence of twowitnesses, at Paris, France, this 13th day of August, 1904.
